CVE-2013-1653 - Remote code execution
* Affected versions: 2.7.0 and greater
* Patched versions: 2.7.x, 3.1.x
A bug in Puppet allows authenticated clients to execute arbitrary code
on Puppet agents that accept kick connections. Puppet agents are not
vulnerable in their default configuration. However, if the Puppet
agent is configured to listen for incoming connections, e.g. listen =
true, and the agent's auth.conf allows access to the `run` REST
endpoint, then an authenticated client can construct an HTTP PUT
request to execute arbitrary code on the agent. This issue is made
worse by the fact that puppet agents typically run as root.
